Cell phone reception in the Minergiehaus is poor

    • Hello everyone

    I have been living in a new building (5630 Muri AG) for around 1.5 years. Since the beginning, cell phone reception in the apartment has been extremely poor (1 to max. 2 bars). This is very difficult. I have activated WLAN calls. That works to some extent. The quality of the call isn’t great either, although the WiFi signal is great. However, cell phone reception is more important to me. This is because I receive a code via SMS for internet banking, for example. To get the code, I go from room to room until I receive an SMS at some point and then I can go back to the PC. Somehow that can’t be the case, can it? How do I get full reception in every room in the apartment? I got a prepaid SIM from Sunrise to test it. The reception isn’t any better either. However, there is the so-called “Sunrise Indoor Box” which promises to improve cell phone reception. Does Swisscom also offer something like this?

    Thank you very much and kind regards

    Nope, Swisscom doesn’t have a box like that.

    Do you live in a Minergie house or something?

    Hello Pogo 1104

    Thank you very much for your answer.

    Yes, it is a Minergie certified house.

    Is this the possible cause of the poor reception?

    Of course it would also be interesting to see how this could be “worked around”. 🙂

    Minergie buildings are known to show your experiences regarding reception

    Colleague Jüre has previously written how you can get around it

    Hello POGO 1104 and Jüre

    Thank you very much for your answers and help.

    In this case I will deal with wifi calling.

    Thanks again.

    Kind regards, Solski

    By (fully) opening one or more windows, mobile phone reception in the room is improved (if windows in a Minergie house can be opened…).

    In buildings, communication should only take place via the mobile phone network if the building is equipped with an in-house antenna or mobile phone repeater. Mobile radio is designed for outdoor use and is not intended for use in buildings!

    For more information on the subject of “mobile radio repeaters” see:

    https://community.swisscom.ch/t5/Mobile/Abbruch-des-telefonat/m-p/636411

    At home, the use of cordless landline telephony with DECT or CAT-iq is recommended:

    https://de.wikipedia.org/wiki/Digital_Enhanced_Cordless_Telecommunications

    https://de.wikipedia.org/wiki/CAT-iq

    When purchasing a cordless landline telephone, pay attention to the functions that reduce radiation exposure.

    I have exactly the same problem.
    I also live in Muri AG.

    Also Minergie.

    Also have to go to the terrace for a dash.
    Swisscom doesn’t want to help me, which I find extremely customer-unfriendly.

    Incoming calls need a dash. Otherwise it won’t work with wificalling.

    Help PLEASE.

    Why that is the case, why Swisscom or No provider can help and what solution there is for you is all explained in the previous articles.

    WiFi calling works without cell phone reception, WiFi alone is enough:

    I’ve experienced it myself…

    That’s why WiFi calling is there, even if there is no cell phone reception. There is no need for at least one line of cell phone reception. At least you can easily test it yourself with Android devices. Switch on airplane mode and then activate the WLAN. Calls also work perfectly, provided of course there is reasonably good WiFi reception.

    For all services in the mobile network, there is now a solution to handle this service via an IP network, such as 4G/LTE, 5G or WLAN/WiFi. For SMS, this solution is called “SMS over IMS”. The most important services for the mobile phone in the IP network are:

    - VoLTE (Voice over LTE) -> Voice telephony over 4G/LTE mobile network https://de.wikipedia.org/wiki/VoLTE

    - VoWLAN (Voice over WLAN), also called VoWiFi (Voice over WiFi) or “WiFi Calling” -> Voice telephony via WLAN/WiFi

    - “SMS over IMS” also called “SMS over IP” (SMSoIP) -> SMS over IP network (4G/LTE, 5G or WLAN/WiFi)

    Whether this service is supported over an IP network depends on the mobile phone, the mobile network and the SIM card. See post no. 7 at:

    [https://community.swisscom.ch/t5/Mobile/4G-VoLTE-telefonieren-mit-externer-antenna-oder-analogem-telefon/m-p/638087#M8203] (https://community.swisscom.ch/t5/Mobile/4G-VoLTE-telefonieren-mit-externer-Antenne-oder-analogem-telefon/m-p/638087#M8203)

    For all of these services, the user data is transmitted exclusively as IP data packets. All of these services require a functioning IMS (see post #22).

    VoWLAN enables voice telephony via the foreign holiday hotel WLAN/WiFi if the data traffic is routed through a VPN tunnel over the home Internet connection. VoWLAN is only possible with the mobile phone provider Swisscom if a public, Swiss IPv4 address is used!

    For technical details about the VPN tunnel see post no. 1065 at:

    [https://community.swisscom.ch/t5/Mobile/Advanced-Calling-VoLTE-und-WiFi-Calling/m-p/533122/highlight/true#M4663] (https://community.swisscom.ch/t5/Mobile/Advanced-Calling-VoLTE-und-WiFi-Calling/m-p/533122/highlight/true#M4663)

    If you have problems with VoWLAN, see article no. 14 under:

    [https://community.swisscom.ch/t5/Mobile/WiFi-Calling-unzuverl%C3%A4ssig-Gem%C3%A4ss-Swisscom-Support-nicht/m-p/580976#M6378] (https://community.swisscom.ch/t5/Mobile/WiFi-Calling-unzuverl%C3%A4ssig-Gem%C3%A4ss-Swisscom-Support-nicht/m-p/580976#M6378)

    For information on radiation exposure when using VoWLAN, see article no. 11:

    [https://community.swisscom.ch/t5/Mobile/WiFi-Calling-unzuverl%C3%A4ssig-Gem%C3%A4ss-Swisscom-Support-nicht/m-p/523044#M4238] (https://community.swisscom.ch/t5/Mobile/WiFi-Calling-unzuverl%C3%A4ssig-Gem%C3%A4ss-Swisscom-Support-nicht/m-p/523044#M4238)

    In general, the use of VoWLAN/VoWifi is not recommended. See “Good Performance Rule” no. 10 and No. 22 under:

    [https://community.upc.ch/d/4397-diagnose-tool-der-connect-box-says-your-home-network-hat-derzeit-einige-probl/27](https://community. upc.ch/d/4397-diagnose-tool-der-connect-box-says-your-home-network-has-currently-some-probl/27)

    It is better to use a “Dual SIM” capable mobile phone with a cheap “roaming SIM card” such as the (no longer available) Swiss Mobile SIM card when abroad.

    https://swiss-mobile.swiss.com/myaccount/rates?l=de

    In Switzerland, the use of “Dual SIM” capable mobile phones is generally recommended:

    [https://community.swisscom.ch/t5/Mobile/2G-Abschaltung-2020-neue-weisse-Flecken-kein-Empfang/m-p/617825#M7418] (https://community.swisscom.ch/t5/Mobile/2G-Abschaltung-2020-neue-weisse-Flecken-kein-Empfang/m-p/617825#M7418)

    For use within Europe, the use of a “Natel FL” SIM card could also make sense (Swisscom Abo for Liechtenstein):

    In my opinion, SMS can also be used via WiFi calling. What I would try (at least it works with Android phones): Put the phone in airplane mode, then only activate WiFi. Then 3G/4G is switched off, the device stays on WIFI and doesn’t switch. This way you can also test whether SMS are arriving, whether calls are being made, etc.

    Simply turn off airplane mode when you leave the house, otherwise you won’t be reachable. But you usually notice it relatively quickly 🙂

    If there is no tick mark from the mobile network at all for Wi-Fi calling, normal SMS does not work on the cell phone. We have already had a few cases with users who did not receive an SMS during telebanking and, for example, Had to move outside to get the code via SMS via mobile network.

    Yes, then I can’t help either. I just tested it: Samsung set it to airplane mode, then activated WLAN again. I’m only connected to WiFi now. Can make calls, receive SMS. In my opinion, the device is no longer connected to the mobile network, so no problem.

    What kind of special SMS the bank sends that needs an anchor in the mobile network… I have no idea.
